DOUBLÉ FELLOWSHIP, as has been said, is concerned in Cases in which the stocks of partners are employed or continued for different times. Questions of this nature frequently occurring in military service, General Haviland, an officer of great merit, contrived an ingenious in. strument, for more expeditiously resolving them; which is distinguish. et by the name of the inventor, being called a Haviland. RULE*-Multiply each person's stock by the time of its continuance; then divide the quantity, as in Single Fe:low. ship, into shares, in proportion to these products, by saying, As the total sumn of all the said products, EXAMPLES 1. A had in company 501 for 4 months, and a had 601 for 5 months ; at the end of which time they find 24i gained : how must it be divided between them? Here 50 60 5 200 + 300 - 500 Then, as 500 : 24 : : 200 : = 91 128 = A's share. and as 500 : 24 :: 300 : 143 B's share. 2. c and o hold a piece of ground in common, for which they are to pay 541. c put in 23 horses for 27 days, and d 21 horses for 39 days ; how much ought each man to pay of the rent ?

Three persons, E, F, G, hold a pasture in common, for which they are to pay 397 per annum; into which e put 7 oxen for 3 months, F put 9 oxen for 5 months, and G put in 4 oxen for 12 months; how much must each person pay of the rent? Ans. E must pay 51 10s 6d 19. 16 10 0.8 12 12 7 2.6 15° 4. A ship's company take a prize of 10001 which they agree to divide among them according to their pay and the time they have been on board : now the officers and midshipmen have been on board 6 months, and the sailors 3 months ; • The proof of this rule is as follows : When the times are equal the shares of the gain or loss are evidently as the stocks, as in Single Fe lowship; and when the stocks are equal, the shares as the times ; Therefore, when neither are equal the shares must be as their products, the 4; 5; 6; When interest is at 3 per cent, the rate is 3; 4 per cent. 6 per cent. But, by law in England, interest.ought not to be taken highcr than at the rate of 5 per cent. Interest is of two sorts; Simple and Compound. Simple Interest is that which is allowed for the principal lent or forborn only, for the whole time of forbearance. As the interest of any sum, for any time, is directly proportional to the principal sum, and also to the time of continue ance ; hence arises the following general rule of calculation. As 1001 is to the rate of interest, so is any given principal to its interest for one year. And again, As 1 year is to any given time, so is the interest for a year, just found, to the interest of the given sum for that time. OTHERWISE. Take the interest of 1 pound for a year, which multiply by the given principal, and this product again by the time of loan or forbearance, in years and parts, for the interest of the proposed sum for that time. Note, When there are certain parts of years in the time, as quarters or months, or days : they may be worked for, either by taking the aliquot or like parts of the interest of a year, or by the Rule of Three, in the usual way. Also to divide by 100, is done by only pointing off two figures for decimals, EXAMPLES. 1. To find the interest of 2302 108, for 1 year, at the rate of 4 per cent. per annum. Here, As 100 : 4 :: 2302 108 : 91 48 4zd. 4 Ex. 2. To find the interest of 5471 158, for 3 years, at 5 per cent. per annum.
